Which factors increase hardenability?

Sep 11,2015 Hardenability of Steel4 Factors Metallurgy#0183;Discussion; Sravanthi -Posted on 12 Nov 15 Different factors affecting hardenability are as follows 1) Alloying elements Hardenability increases due to presence of alloying elements in steel.Carbon,manganese,chromium,silicon,nickel,vanadium,etc are the different alloying elements used in steel.Welding Metallurgy of Carbon SteelsWhen welded at higher heat inputs (100 60 kJ/cm),impact toughness values of the steel without Nb are much higher than those of the steel with Nb,and the lowest span is 153 J at 60 kJ/cm.But Welding Metallurgy of Carbon Steels - Welding Engineering Each diagram is only applicable to a single steel composition.There are a number of factors that control the hardenability of a steel.Alloying additions have the greatest effect on hardenability because they are effective in delaying the transformation to other transformation products (ferrite,

Machinability,Weldability,and the Abilities of Steel

Castability of Steel.The castability of steel refers to the ease of forming qualified workpieces by casting.It is affected by the properties of fluidity,shrinkage and segregation..The fluidity of steel is defined as the ability of molten steel to fill mould cavities.; Shrinkage refers to the extent of volume reduction when the molten steel solidifies.A low rate of shrinkage is favourable Inter-Relationship Between Weldability And Hardenabilityquench,whereas a steel of low hardenability may only form a high fraction of martensite to a depth of less than a millimeter,even under rapid cooling such as a water quench.Hardenability therefore describes the capacity of the steel to harden in depth under a given set of conditions.[4-7] Steels with high hardenability are needed for large highIncluding results for hardenability of steel factors metallurgy.Do you want results only for Hardenability of Steel4 Factors Metallurgy?Hardenability of Steel 4 Factors Metallurgy Grain Size Grain boundaries are the preferential nucleation sites for ferrite and pearlite.IfAustenitising Temperature and Time The beneficial effects of the alloying elements in steel inCarbon Content of the Steel Carbon fixes the maximum attainable hardness on quenching.It alsoAlloying Elements in Steel Most metallic alloying elements (except cobalt) slow down the ferriteHardenability - an overview ScienceDirect TopicsR.E.Smallman,A.H.W.Ngan,in Modern Physical Metallurgy (Eighth Edition),2014.12.9.2 Factors affecting hardenability.Any factor that moves the nose of the TTT curve to longer times will increase the hardenability of the steel.The important factors are (i) carbon content,(ii) austenite grain size and (iii) alloy composition.
